Books if you loved the Old kingdom series

I recently read Garth Nix's old kingdom series and I was totally hooked on the necromancy parts. I know it's not the greatest series out there, but it was easy and light to read and i thoroughly enjoyed it. Haters don't come at me 🙈

Any recommendations in this space. Necromancy/Death walkers etc? Would love standalone or series, but unputdownable of sorts

Thank you!
